Beam quality: no dataTarget: The targets of 148Nd were made by vacuum evaporating enriched isotopes onto 20 mkg/cm2 carbon backings. The thickness was about 30 mkg/cm2 for 148Nd and the enrichment was 93.7%.Data obtained: author's graph digitizedThe experiments were performed at the HI-13 tandem accelerator of China Institute of Atomic Energy with a G120L-QDDD magnetic spectrometer.
